This happens to my Toby too. First of all, he is a year and a half and they think he is a puppy. Usually places like the bank and McDonalds will give him a dog bone, but the other day I went through Dunkin Donuts Drive thru and they wanted to give him a glazed munchkin. I felt the same way regarding the healthiness of it and ate it myself!
BY no means does he need sugar! He is already energetic enough.
